Using the James Webb Space Telescope (JWST), astronomers have spotted a supermassive black hole at "cosmic dawn" that seems to be impossibly massive. The confusion comes from the fact that it doesn't seem like this giant void was feasting on much surrounding matter during that time — but, in order to reach its immense size, one would expect it to have been ravenous when time began.
The feeding supermassive black hole, which powers a quasar at the heart of the galaxy J1120+0641, was seen as it was when the universe was just around 5% of its current age. It also has a mass that is over a billion times that of the sun.
